Iím not gonna argue with you on the math. You can try to explain it to AE. Look at page 22 of a TC3/4 manual. AE has the final drive listed as 2.5:1. So if you are putting TC3/4 gear in your Pro4 change both front and rear.

I know we all love the Pro4 here, but heres my question.

I assume that certain cars are perceived as 1st class cars, and then tehre are the next level down, and so on...

The Pro4 if not the best, then one of the best 1/10 EP cars.

Which cars are at the top with the Pro4, and which would fall in the classes below?

I hope this makes sense?

I would think that any TC over the price of $250 would be in the same "class" as the Pro4,05FK,RDX,415MXS..etc

unfortunately no...
I've asked HPI if there is any plans for aluminum bulkhead like the evo's and SD's... they have no plans to do so...

why would you want AL bulkheads? any benefits will be outweighed by the substantial weight increase (at least if you keep it fully sealed, and if you dont keep it sealed you're REALLY sacrificing and even then i doubt you could get the weigh equally light as crp)

the dhi 05' setup seems to be good for one-way tracks (flowey and non super sharp corners). its one of the only setups i've seen to use anti-dive in the front which to me reinforces that it was made for higher speed tracks (anti-dive to prevent too much front weight xfer). seems to be made to have fast cornering speeds.
for small tracks i dont think its the ticket because of the one-way. and if you swap out the one-way you're gonna change the handlig characteristic so much that you'd prolly do better to find a spool setup as a baseline instead of this one.

Come on floodo1, you of all people should know, it's all about the bling bling. And possibly more freespin from the precise bearings alignment.

Ahhh... more freespin! As if 8 million seconds isn't enough! I know I have a lot of freespin, but I'm curious. What things would I be able to lighten in the drivetrain... I've got blue tc3 bones up front, composite tc3 bones in back, aluminum input shafts, delrin rear cups, front one way... Is there anything I can lighten to take advantage of my drivetrain?
